    Need Help Converting AAC to MP4

    I tried converting some AACs to m4a and I wound up with file sizes roughly twice as large as the originals.

    -I selected to convert to m4a Nero (AAC)
    -using neroAacEnc.exe as the encoder
    -no forced profile

    Am I doing this correctly? I thought this process was just changing the container (which I only vaguely understand), so why all the encoding time and much bigger file sizes?

    I used the two following threads to try to figure things out, but it seems I'm doing something wrong here:

    I really appreciate any help, thanks

    Converting t m4a Nero (AAC) actually decodes and reencodes.

      I figured that's what was happening. Is there a way to go aac > m4a without decoding and reencoding?

        I should also add that I have hundreds of such conversions in a folder structure I would like to retain, so file by file, command line solutions will not work.

          This can shift aac in and out of the m4a container.

            Thanks so much. One AAC file coded as ADTS didn't convert. Is there a way to do this?
